I'm building a GC, both amps powered by one transformer 2x25v. I want 35v supply to the amps. It seems that I have 2 or 3 basic options for an unregulated circuit, e.g.: 1 bridge; 2 bridges with single 0v rail; 2 bridges with 2x 0v rails... Can anyone please advise a suitable schematic for this purpose? I assume that one bridge per secondary is best, and that I need caps after them to get the voltage increase.
Thanks!
Thanks!

You decide at the end. Now I most likely do the simpler version (one PS with one bridge for both channels). Get it working first and if you decide to improve at least you'd have some reference point. I you use reasonable power (up to 30-40W), don't be surprised if you don't hear any difference between the different PS. You kan still use 1000uF rail caps for each channel (total of 2000 per rail). Though, again you're free to experiment and go up to 10000 per rail if you want. Again, depends on how much power you need to pump into the speakers.
